Abstract

1. Device for evacuation of burnt gas and admission of fresh air for sealed gas type heating apparatuses comprising two orientable concentric conduits of which an interior conduit is connected to a vertical flue for evacuation of burnt gases eccentrically with respect to the heating body and constituted by the upper part of a canopy having a profile in the shape of an L, and of which an outer conduit defines with the interior conduit an annular space for admission of fresh air into the sealed enclosure of the apparatus by means of an air distribution box, the seal being ensured by an outer cap, characterised by the fact that the air distribution box (15) of small thickness and of parallelepipedonal form is fixed horizontally at the top of said flue (12), in that it substantially closes all of the upper face of the sealed chamber, equivalent to the base surface of the canopy thus providing an interior space in which is disposed the extraction fan (5) whose outlet passage passes through the distribution box and in that it is provided on its lower wall with orifices (17) for air flow.

Description

L'invention se rapporte à une hotte d'évacuation des gaz brûlés associée à un boitier répartiteur d'air de combustion pour appareils étanches à gaz.The invention relates to a flue gas exhaust hood associated with a combustion air distribution unit for gas-tight devices.

On sait que dans le cas des appareils à gaz à chambre de combustion étanche du type à tirage forcé par un ventilateur électrique, l'arrivée de l'air de combustion et l'évacuation des produits de combustion se font très souvent à l'aide de deux conduits concentriques ou coaxiaux. Le conduit intérieur qui a précisément un diamètre plus petit que le conduit extérieur est généralement utilisé pour l'évacuation des gaz chauds constituant les produits de la combustion du gaz, l'air nécessaire à la combustion circule en sens inverse dans l'espace compris entre le conduit intérieur chaud et le conduit extérieur froid.It is known that in the case of gas appliances with a sealed combustion chamber of the type with forced draft by an electric fan, the arrival of combustion air and the evacuation of combustion products is very often done using of two concentric or coaxial conduits. The internal duct which has a precisely smaller diameter than the external duct is generally used for the evacuation of the hot gases constituting the products of the combustion of the gas, the air necessary for combustion circulates in the opposite direction in the space between the hot interior duct and the cold exterior duct.

Cette disposition est avantageuse car elle permet de raccorder l'appareil à une microventouse placée à l'extérieur du mur du logement en ne perçant dans ce dernier qu'un simple trou rond de faible diamètre.This arrangement is advantageous because it makes it possible to connect the device to a micro-cup placed outside the wall of the housing by drilling in the latter only a simple round hole of small diameter.

De plus la microventouse également à structure coaxiale est plus simple à fabriquer et présente un encombrement minimum.In addition, the microvalve also with a coaxial structure is simpler to manufacture and has a minimum size.

Ce type de raccordement d'un appareil à gaz étanche par tubes coaxiaux sur une ventouse elle-même coaxiale placée sur la face extérieure d'un mur est possible dans tous les cas d'implantation de l'appareil grâce à des coudes orientables également formés de tronçons coudés coaxiaux comme décrits dans le brevet français n° 2.350.539 au nom de la demanderesse.This type of connection of a sealed gas appliance by coaxial tubes on a suction cup itself coaxial placed on the outside face of a wall is possible in all cases of installation of the appliance thanks to adjustable bends also formed of coaxial bent sections as described in French Patent No. 2,350,539 in the name of the Applicant.

Ce coude orientable est généralement monté sur la sortie du ventilateur d'extraction des gaz brûlés lui-même fixé à la hotte d'évacuation, l'air frais étant admis à l'extérieur de la hotte et recyclé vers les brûleurs à l'intérieur de l'enceinte étanche. Ou encore le coude est monté directement sur la hotte et le tube d'évacuation porte le ventilateur d'extraction.This adjustable elbow is generally mounted on the outlet of the exhaust gas exhaust fan itself fixed to the exhaust hood, fresh air being admitted outside the hood and recycled to the burners inside of the waterproof enclosure. Or the elbow is mounted directly on the hood and the exhaust tube carries the exhaust fan.

Dans ces dispositions connues se pose notamment le problème de l'accessibilité du ventilateur d'extraction, rendue difficile sans démonter justement ces raccords orientables. En outre les. hottes utilisées jusqu'à présent, qui ont par nécessité une forme de coiffe pour recueillir les gaz de combustion et les amener vers l'orifice de sortie, supportent généralement sur leur face inclinée ledit ventilateur, rendant son entretien ou son réglage difficile. De plus l'enceinte étanche proprement dite doit donc envelopper cette hotte et le ventilateur : elle présente de ce fait une dimension relativement importante avec un espace inutile à la partie supérieure.In these known arrangements, there is in particular the problem of the accessibility of the extraction fan, which is made difficult without precisely dismantling these orientable fittings. In addition the. hoods used until now, which by necessity have a cap shape to collect the combustion gases and bring them to the outlet orifice, generally support said fan on their inclined face, making maintenance or adjustment difficult. In addition, the actual sealed enclosure must therefore surround this hood and the fan: it therefore has a relatively large dimension with an unnecessary space at the top.

Enfin dans cette disposition le ventilateur est généralement à axe incliné ce qui est préjudiciable à son bon fonctionnement en atmosphère chaude.Finally, in this arrangement, the fan is generally with an inclined axis, which is detrimental to its proper functioning in a hot atmosphere.

Ces inconvénients ont conduit la demanderesse-à repenser le problème de la hotte d'évacuation des gaz brûlés, vis-à-vis du montage du ventilateur d'extraction et de l'admission d'air frais, pour qu'il soit compatible avec l'utilisation d'un coude de raccordement orientable, et cela pour tenir compte des exigences modernes de ce genre d'appareils dans le domaine de la simplicité et de la compacité.These drawbacks have led the plaintiff to rethink the problem of the exhaust hood for the exhaust gases, with respect to the mounting of the exhaust fan and the intake of fresh air, so that it is compatible with the use of an adjustable connection elbow, and this to take account of the modern requirements of this kind of apparatus in the field of simplicity and compactness.

Le dispositif d'évacuation selon l'invention est essentiellement constitué d'une hotte ayant un profil en forme de L, d'une chambre collectrice, disposée immédiatement au-dessus du corps de chauffe de l'appareil, dont le couvercle supérieur est faiblement incliné sur l'horizontale, d'une cheminée verticale d'évacuation surmontant ledit couvercle, et d'un boîtier répartiteur d'air disposé à plat à la partie supérieure de la cheminée. Selon une caractéristique particulière de l'invention, sur une paroi verticale de la cheminée est monté le ventilateur d'extraction et son moteur d'entraînement à axe horizontal, coiffant un orifice prévu sur la cheminée, et dont la tubulure de sortie traverse le bottier répartiteur d'air pour s'emmancher sur le conduit intérieur du coude orientable, le ventilateur étant ainsi avantageusement logé dans l'espace creux entre le couvercle de la chambre collectrice, la cheminée et le répartiteur d'air, son axe étant horizontal ce qui améliore sa longévité. En outre, grâce à cette disposition, le coude orientable de sortie de gaz peut être orienté en toutes directionsce qui est avantageux notamment pour la rénovation des locaux anciens.The evacuation device according to the invention essentially consists of a hood having an L-shaped profile, a collecting chamber, disposed immediately above the heating body of the apparatus, the upper cover of which is slightly inclined to the horizontal, a vertical exhaust chimney surmounting said cover, and an air distributor box arranged flat at the top of the chimney. According to a particular characteristic of the invention, on a vertical wall of the chimney is mounted the exhaust fan and its drive motor with a horizontal axis, covering an orifice provided on the chimney, and the outlet of which passes through the case air distributor to be fitted onto the inner duct of the adjustable elbow, the fan thus advantageously being housed in the hollow space between the cover of the collecting chamber, the chimney and the air distributor, its axis being horizontal which improves its longevity. In addition, thanks to this arrangement, the adjustable gas outlet elbow can be oriented in all directions, which is advantageous in particular for the renovation of old premises.

D'autres caractéristiques particulières et avantages de l'invention ressortiront de la description suivante d'une forme de réalisation en référence au dessin annexé qui représente une vue partiellement écorchée en perspective de la hotte d'évacuation.Other particular characteristics and advantages of the invention will emerge from the following description of an embodiment with reference to the appended drawing which represents a view partially skinned in perspective of the exhaust hood.

Cette hotte est désignée dans son ensemble par la référence 1, elle coiffe le bloc à ailettes 2 qui constitue le corps de chauffe de l'appareil. Elle présente un profil en forme de L dont la partie inférieure de forme rectangulaire, fixée au bloc à ailettes, forme la chambre collectrice 10 dont le couvercle supérieur 11 est faiblement incliné sur l'horizontale. Une cheminée verticàle d'évacuation 12 prolonge vers le haut ladite chambre collectrice. La paroi latérale est en outre fermée à sa partie supérieure par une plaquette horizontale 14. Sur cette dernière est fixé un boîtier répartiteur d'air 15 de forme parallélépipédique et d'épaisseur réduite qui, en plus, a une surface équivalente à la surface de base de la hotte. La face supérieure de ce boîtier est percée d'un orifice 16 pour l'évacuation des-gaz brûlés et l'admission d'air frais. Cet orifice est coiffé d'un coude de raccordement orientable 3, connu en soi, dont le conduit intérieur 4 de plus petit diamètre traverse de façon étanche tout le boîtier 15 pour s'emmancher sur le tube de sortie du ventilateur d'extraction 5. Par contre le conduit extérieur 6 du coude orientable couvre la totalité de l'orifice 16 pour que l'air frais admis par l'espace annulaire compris entre les conduits 4 et 6 pénètre dans le boîtier répartiteur 5. Enfin des orifices 17 sont prévus sur la paroi inférieure du boîtier 15 pour le passage de l'air de combustion en direction des brûleurs, extérieurement à la hotte 1. Sur ces orifices 17 peuvent en outre être rapportés des petits tubes de prise d'air notamment pour la surveillance du débit et la sécurité de l'appareil. Le ventilateur d'extraction 5 est fixé à la paroi latérale de la cheminée 12 au-dessus de l'orifice 13. Le moteur 7 d'entrainement de la turbine 8 dudit ventilateur est lui-même monté sur le capot du ventilateur d'extraction 5. Il occupe ainsi l'espace creux disponible entre le couvercle 11 de la chambre collectrice 10, la cheminée 12 et le boîtier répartiteur d'air 15. Il est à axe horizontal ce qui le rend aisément accessible et démontable et lui garantit un bon fonctionnement. L'ensemble précédemment décrit, que constitue la hotte et le boîtier répartiteur d'air est fixé au dossier 9 de l'appareil contre lequel est destiné à s'appliquer de façon étanche le capot extérieur 20. Sur la face supérieure du boîtier répartiteur d'air 15 est prévu à cet effet une barrette 18 qui couronne le coude orientable 3 et sert de support à un joint d'étanchéité 19 contre lequel s'applique le capot 20. La face supérieure de ce dernier est évidemment échancrée et conformée pour correspondre au profil de la barrette.This hood is designated as a whole by the reference 1, it covers the fin block 2 which constitutes the heating body of the device. It has an L-shaped profile, the lower part of which is rectangular, fixed to the fin block, forms the collecting chamber 10, the upper cover 11 of which is slightly inclined to the horizontal. A vertical exhaust chimney 12 extends upwards said collecting chamber. The side wall is further closed at its upper part by a horizontal plate 14. On the latter is fixed an air distributor housing 15 of parallelepiped shape and reduced thickness which, in addition, has an area equivalent to the area of base of the hood. The upper face of this housing is pierced with an orifice 16 for the evacuation of the burnt gases and the admission of fresh air. This orifice is capped with an orientable connection elbow 3, known per se, whose inner duct 4 of smaller diameter passes through the entire housing 15 in leaktight manner to fit onto the outlet tube of the exhaust fan 5. On the other hand, the external conduit 6 of the orientable elbow covers the whole of the orifice 16 so that the fresh air admitted by the annular space between the conduits 4 and 6 enters the distributor box 5. Finally, orifices 17 are provided on the lower wall of the housing 15 for the passage of combustion air towards the burners, outside the hood 1. On these orifices 17 can also be added small air intake tubes in particular for monitoring the flow rate and device security. The exhaust fan 5 is fixed to the side wall of the chimney 12 above the orifice 13. The motor 7 for driving the turbine 8 of the said fan is itself mounted on the hood of the exhaust fan 5. It thus occupies the hollow space available between the cover 11 of the collecting chamber 10, the chimney 12 and the air distributor housing 15. It has a horizontal axis which makes it easily accessible and removable and guarantees it good operation. The assembly described above, which constitutes the hood and the air distributor box is fixed to the backrest 9 of the device against which is intended to be applied in a sealed manner. outer cover 20. On the upper face of the air distributor housing 15 is provided for this purpose a bar 18 which crowns the adjustable elbow 3 and serves as a support for a seal 19 against which the cover 20 applies. upper face of the latter is obviously notched and shaped to match the profile of the bar.

Quand le capot 10 est appliqué de façon étanche au dossier 9 de l'appareil, durant le fonctionnement, le ventilateur 5 extrait vers le conduit 4 les gaz brûlés collectés par la hotte 1, par l'intermédiaire de l'orifice 13 prévu sur la cheminée 12. La répartition de l'aspiration des gaz brûlés sur l'ensemble du bloc à ailettes 3 (du fait que la cheminée 12 n'est pas centrée sur ce bloc à ailettes) est facilitée par la pose, -à l'intérieur de la chambre collectrice 10-, d'au moins un volet déflecteur 21 incliné sur l'horizontale.When the cover 10 is applied in a sealed manner to the backrest 9 of the device, during operation, the fan 5 extracts towards the duct 4 the burnt gases collected by the hood 1, by means of the orifice 13 provided on the chimney 12. The distribution of the suction of the burnt gases over the whole of the fin block 3 (owing to the fact that the chimney 12 is not centered on this fin block) is facilitated by the installation, inside of the collecting chamber 10-, of at least one deflector flap 21 inclined on the horizontal.

L'extraction des gaz de combustion entraîne l'aspiration d'air frais par l'espace annulaire entre les tubes 4 et 6 vers le bottier répartiteur d'air 15. Comme son nom l'indique le boitier répartiteur permet la répartition de l'air aspiré vers une pluralité d'orifices 17, cet air continuant en un mouvement descendant vers les brûleurs non représentés, en léchant les parois extérieures de la hotte et du corps de chauffe.The extraction of the combustion gases entails the suction of fresh air through the annular space between the tubes 4 and 6 towards the air distributor casing 15. As its name indicates the distributor casing allows the distribution of the air sucked towards a plurality of orifices 17, this air continuing in a downward movement towards the burners not shown, by licking the external walls of the hood and of the heating body.

Cette disposition présente l'avantage d'assurer une ventilation permanente du moteur 7. Quand on enlève le capot 20 on accède aussitôt au ventilateur d'extraction et à son moteur, facilement démontables de la hotte à laquelle ils sont fixés. L'encombrement de la hotte et du système d'extraction est donc très réduit et va dans le sens d'une recherche d'appareils plus simples et plus compacts.This arrangement has the advantage of ensuring permanent ventilation of the motor 7. When the cover 20 is removed, the exhaust fan and its motor are immediately accessible, easily removable from the hood to which they are fixed. The size of the hood and the extraction system is therefore very small and goes in the direction of a search for simpler and more compact devices.

L'invention ne se limite pas à la forme de réalisation représentée mais en englobe au contraire toutes les variantes constructives.The invention is not limited to the embodiment shown but on the contrary encompasses all the constructive variants thereof.
